fair/obvious warnings

i literally saw no one talk about the pvz lore in somewhat weird detail so I'm gon be the one to do it. (warning: plants vs zombies(pvz) is owned by popcap/ea, also this thing is heavily based on pvz 1, pvz 2 and gw 1+2 i will not talk about the facebook spin off, the potential existing pvz 3 and battle for neighborvile, as they don't hold much lore to my knowledge atleast)
